Ah, I see.

So would it be better to set Prime95 to only Trial Factoring, or would it be better to keep letting PrimeNet decide what to assign ?

Greets,

Windows x64 better for Prime95 ?

Hi,

I'm currently running 2 instances of Prime95 on my new dualcore Pentium D 945. This CPU supports EM64T, but it is currently running a normal (32-bit) Windows XP Home. Would Prime95 benefit...

One thing I would like to add is that laptops (and especially P4's) have a pretty intensive venting set-up, which usually also attracts a lot of dust. In my laptop, it worked fine the first few...

Yeah, it does that on my computer too. With the same version of gmp-ecm under cygwin.

But since I do stage one on Prime95 with the GmpEcmHook, I first do 10 curves stage 1 and then transfer the...

Thanks for your reply geoff. After some tests it seems that my self compiled version was slightly slower on stage1 and slightly faster on stage2 than the link you gave me. (Slightly is a few seconds...

Hmm, I have three little questions.

I think I noticed somewhere that gmp-ecm is slower in stage 1 than Prime95, but gmp-ecm is waaaaay faster in stage 2. Is this correct ?

Does the advantage of...

Oh, IC, but then how do you know that the resulting cofactor is composite ? It seems to me that if you find a factor of a Mersenne number, it always a relatively small number (compared to the...

Little Question

In the lists of not completely factored Mersenne numbers, how do you know that the remaining cofactor is composite ?

So, what I'm asking is actually this : if I were to find a new factor (of the...

Pocket PC

I don't suppose there is a Windows CE (Pocket PC) version of the Prime95 software ?

The reason I ask is because I recently bought one and it seems to have a 400Mhz processor, which would be quite...

If I'm not mistaking (and correct me if I'm wrong, George), the FactorOverride parameter is ignored when you use PrimeNet. If "Use Primenet" is unchecked, the program will factor from the number in...

First stage only uses B1 and all factors of k have to be below B1.
Stage two is a little more general and allows for 1 of the factors of k to be above B1, but still...
